Hello, all! I just purchased the game tonight and I went to explore other maps. However, when I went back to play the default set (which includes the actual Risk map), I couldn't find it. What is the name of the map set, and/or how else can I get back to those maps?

The "original" map should be the map "classic" (it is the map based on the classic board game risk).
The usual Settings for this map are
Cards: 4,6,8,..
Continent boni increasement: 0%
But feel free to try different Settings and maps. Lux has over 800 maps.

If you have purchased the game you are also able to play online with other Players
